Spectrophotometer raw data

I guess we weren’t sure if I was actually drawing rhodamine back through the membrane or just bleaching it. So I made a new apparatus which consisted of a sawed off sepcon mounted on a slide with channels etched into the lower plastic of the device to connect a pbs resevoir on the slide to…

Intro/Motivation:   SiR-Hoechst is a far-red DNA stain for live-cell micro/nanoscopy and has been shown to be non-cytotoxic. I mentioned to Tom that if we can label the cells we can better automate the cell tracking for faster analysis. Tom knew of this dye and decided to give it a try. This direction subsequently lead to a potential…

Summary This post complements Fabricating 0.5 um Channels in Microscope Slides for Staph Invasion Assays. Challenges in the etch transfer process necessitated switching to a different substrate that had stronger selectivity. With that in mind, we set out to create 500×500 nm channels in silicon wafers for the bone invasion study. We had partial success (micron-sized…

As a quick update on the ECM masking with Parylene membrane, we made changes to the device designs. Instead of relying on the peel-off process, we used a simplified design, with the membrane serving as the roof of the channels. Here is the latest design:   For these experiments we continued to use relatively low…

Here are the updated pore processing graphs: The data spreadsheet: pore-processing-results Supplement (added 6/16/09): Here is the Average Pore Size vs. Porosity graph with the outlying data points labeled: After making this graph, I looked at the outliers to see if they were due to my errors. A few were and I redid them, updating the…
